To identify extreme heat areas in the City of Portsmouth, Virginia.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This polygon layer was developed from temperature and heat index rasters created by Heat Watch Portsmouth and CAPA Strategies Heat Watch Program. Data was collected during three time periods (6-7 am, 3-4 pm, and 7-8pm) on July 15, 2024. Temperature points collected were processed with an Area-Wide Model, creating three temperature and three heat index rasters. These where converted to polygons and then unioned together to create this layer.</SPAN></P></DIV></DIV></DIV>
